[0045] Referring to Figure 1 The mobile energy storage container of the present embodiment includes a container body 10.

[0046] The container body 10 can be a standard size container. The standardization of the size of the container body 10 makes the container body 10 have universality and can be adapted to more transportation tools, better meeting the transportation requirements. The specific size of the container body 10 can be set according to actual needs. The container body 10 in the present embodiment can be a standard 20-foot container or a non-standard container.

[0047] Referring to Figure 2 The container body 10 includes a battery cabin 11, a liquid cooling machine cabin 12, and a fire-fighting equipment cabin 13. The battery cabin 11 is arranged at one end of the container body 10, and the liquid cooling machine cabin 12 and the fire-fighting equipment cabin 13 are arranged at the other end of the container body 10.

[0048] The liquid cooling machine cabin 12 is provided with a liquid cooling machine group 2, a liquid cooling pipeline, a fan for cooling the liquid cooling machine group 2, etc., for protecting the temperature of the battery cabin 11 and preventing the battery in the battery cabin 11 from thermal runaway.

[0050] Referring to Figure 3 Along the transverse direction of the container body 10, the two ends of the container body 10 are provided with end walls. For the convenience of description, the end wall close to the end of the container body 10 near the vehicle head is defined as the first end wall 15, and the end wall away from the end of the container body 10 away from the vehicle head is defined as the second end wall 16.

[0051] The battery cabin 11 is arranged away from the front of the vehicle. In other words, the liquid cooling machine cabin 12 and the fire-fighting equipment cabin 13 are arranged close to the front of the vehicle. It can be understood that the liquid cooling machine cabin 12 and the fire-fighting equipment cabin 13 are arranged close to the first end wall 15.

[0052] Continuing to refer to Figure 2 and in combination Figure 1 In some embodiments, the liquid cooling machine cabin 12 and the fire-fighting equipment cabin 13 are arranged close to the corners of the box 10, respectively. An exhaust air passage 14 is arranged between the liquid cooling machine cabin 12 and the fire-fighting equipment cabin 13. Further, the exhaust air passage 14 is formed by the side wall of the liquid cooling machine cabin 12 and the side wall of the fire-fighting equipment cabin 13 being arranged opposite to each other. The exhaust air passage 14 is in communication with the battery cabin 11.

[0053] The arrangement of the exhaust air passage 14 facilitates the flow of the smoke towards the direction of the exhaust fan 3, which is conducive to accelerating the exhaust efficiency of the smoke. It should be noted that in other embodiments, the arrangement of the exhaust air passage 14 can be cancelled, and the liquid cooling machine cabin 12 and the fire-fighting equipment cabin 13 can be arranged adjacent to each other, and an exhaust air duct can be arranged in the fire-fighting equipment cabin 13. The specific arrangement can be set according to actual needs, which is not limited herein.

[0054] The mobile energy storage container comprises at least one exhaust fan 3. At least one exhaust air outlet is arranged on the end wall close to the exhaust air passage 14, i.e. the first end wall 15. The exhaust fan 3 is arranged on the exhaust air outlet. When the battery cabin 11 experiences thermal runaway, the exhaust fan 3 operates, and the combustible gas, smoke, etc. in the battery cabin 11 can be exhausted from the exhaust fan 3 along the exhaust air passage 14.

[0055] It can also be understood that the exhaust fan 3 is arranged between the front of the vehicle and the vehicle frame, so as to make full use of the space between the front of the vehicle and the vehicle frame, and improve the space utilization of the mobile energy storage vehicle.

[0056] Practically, two exhaust air outlets can be arranged. One of the exhaust air outlets is arranged close to the top of the box 10, and the other exhaust air outlet is arranged close to the bottom of the box 10. Correspondingly, the exhaust fan 3 arranged on the exhaust air outlet is provided with two, which can increase the exhaust efficiency of the smoke.

[0057] Referring to Figure 1 , along the transverse direction of the box 10, first side doors 17 are arranged on both sides of the battery cabin 11. Second side doors 18 are arranged on the liquid cooling machine cabin 12. Third side doors 19 are arranged on the fire-fighting equipment cabin 13. The user can install and maintain the equipment in each cabin by operating the doors of the corresponding cabin.

[0058] Referring to Figure 2 and Figure 3The battery cabin 11 is provided with a plurality of battery clusters 4. The plurality of battery clusters 4 are arranged adjacently. That is, a non-step-in design is adopted, and the overpass in the conventional arrangement is cancelled in the box body 10, so that more battery clusters 4 can be placed to improve the space utilization of the battery cabin 11 and facilitate the improvement of the power storage capacity of the energy storage container.

[0059] The plurality of battery clusters 4 can be arranged in a horizontal array or arranged in a vertical stack. For the sake of description, the plurality of battery clusters 4 arranged in a horizontal array is defined as a first arrangement structure, and the plurality of battery clusters 4 arranged in a vertical stack is defined as a second arrangement structure. The plurality of battery clusters 4 in the embodiment is taken as an example of the first arrangement structure.

[0060] Each battery cluster 4 includes a high-voltage box 41 and a plurality of battery boxes 42 connected in series. Each battery box 42 includes a plurality of battery cells. It should be noted that the number of battery clusters 4 and the number of battery boxes 42 can be set according to actual needs. The embodiment takes 10 battery clusters 4 as an example, and each battery cluster 4 includes 8 battery boxes 42.

[0061] In each battery cluster 4, the plurality of battery boxes 42 connected in series form a battery module. The battery module is electrically connected with the high-voltage box 41. The high-voltage box 41 is used to collect voltage, temperature and other data of the battery module, and to realize protection, charge and discharge management and other functions of the battery module, which is safe and reliable.

[0062] In practice, the plurality of battery clusters 4 is in the first arrangement structure. Specifically, the high-voltage box 41 and the plurality of battery boxes 42 in the battery module are arranged in a vertical direction of the box body 10. Thus, the 10 battery clusters 4 form a matrix of 2 rows and 5 columns.

[0063] In addition, referring to Figure 1 As shown, the first side door 17 includes a plurality of small doors 171, and each small door 171 is arranged corresponding to each battery cluster 4 in a single column. That is, in the embodiment, the small door 171 on one side of the box body 10 is provided with 5 small doors. The user can install and maintain the high-voltage box 41 and the battery box 42 of each battery cluster 4 by operating the small door 171, which is relatively convenient to operate.

[0064] As shown in Figure 3 and in combination with Figure 1 The high-voltage box 41 is located at the bottom of the battery module. That is, the high-voltage box 41 is arranged close to the bottom of the box body 10. Since the mobile energy storage container is arranged on the frame, the bottom of the mobile energy storage container is a certain height from the ground, so that the high-voltage box 41 is arranged close to the bottom of the box body 10, so that the operator does not need to bend down or squat to operate and maintain the high-voltage box 41.

[0065] It should be noted that in other embodiments in which the plurality of battery clusters 4 are arranged in the first arrangement, the high-pressure tank 41 can also be arranged at the top of the battery module. The specific arrangement can be determined according to actual needs, and is not limited herein.

[0066] The mobile energy storage container includes pressure relief windows 5. The pressure relief windows 5 are arranged at the top of the box 10. When the pressure or temperature inside the box 10 reaches a threshold value, the pressure relief windows 5 operate to release the internal pressure or temperature to the outside of the mobile energy storage container, thereby maintaining the safety of the mobile energy storage container.

[0067] The pressure relief windows 5 are arranged at the top of the battery cabin 11, so that when the pressure relief windows 5 are activated, damage to personnel around the mobile energy storage container can be effectively avoided.

[0068] The pressure relief windows 5 are arranged in a plurality. The number of pressure relief windows 5 can be consistent with the number of small doors 171 arranged on one side of the battery cabin 11. That is, one pressure relief window 5 is arranged at the top of each single-row battery cluster 4. It can be understood that in the present embodiment, the pressure relief windows 5 are arranged in five.

[0069] The plurality of pressure relief windows 5 can be staggered. That is, the pressure relief windows 5 at the top of adjacent two-row battery clusters 4 can be arranged in a staggered manner.

[0070] Referring to Figure 4 , Figure 4 In another embodiment of the mobile energy storage container, the plurality of battery clusters 6 are arranged in a second arrangement, which is different from the above-described embodiments. That is, the plurality of battery clusters 6 are arranged in a vertical and stacked manner.

[0071] Specifically, the plurality of batteries 62 in the battery cluster 6 are connected in series to form a battery module. The high-pressure tank 61 is arranged in the same plane as the plurality of battery boxes 62 of the battery module. The battery boxes 62 in the battery module are arranged in the transverse direction of the box 20. In the same horizontal plane, two battery clusters 6 can be arranged in the box 20.

[0072] In the present embodiment, 14 battery clusters 6 are arranged in the box 20, and each battery cluster 6 includes five battery boxes 62. Referring to Figure 5 and Figure 6 , Figure 5 and Figure 6 are respectively Figure 4 the front view and the rear view of the mobile energy storage container shown in FIGS. 1 and 2. The high-pressure tank 61 is arranged at one end of the battery module. The plurality of high-pressure tanks 61 are arranged in the vertical direction of the box 20.

[0073] In some embodiments, the high-voltage box 61 can be arranged close to the second end wall 16 of the box body 20. The second end wall 16 is the end wall of the box body 20 away from the front end of the vehicle. In other words, the high-voltage box 61 is arranged at the end of the box body 20 away from the front end of the vehicle to facilitate wiring. At the same time, it also means that the battery box 62 is arranged in the middle of the box body 20, which is beneficial to protect the battery box 62 from being directly impacted.

[0074] It should be noted that the length of the box body 20 adopting the second arrangement structure of the plurality of battery clusters 6 is greater than the length of the box body 10 adopting the first arrangement structure. Specifically, if the 20-foot standard container is still taken as an example, the length of the box body 20 needs to be extended to place the high-voltage box 61. The extended length can be 800 mm. It can be understood that the box body 20 in the present embodiment is a non-standard container. In other embodiments, the specific length to be extended can be set according to actual needs, for example, considering the size of the high-voltage box 61, the size of the battery box 62, etc., which is not limited herein.

[0075] In addition, it can be understood that the box body 20 can also be a standard container. The size of the standard container is greater than that of the 20-foot standard container, and the high-voltage box 61 can be placed therein.

[0076] In the present embodiment, the first side door (not shown in the figure) arranged on both sides of the battery cabin 11 still includes a plurality of small doors (not shown in the figure). The small door on one side of the battery cabin 11 corresponds to the battery box 62 and the high-voltage box 61 contained in each battery cluster 6. In other words, the number of small doors is equal to the number of high-voltage boxes 61 plus the number of battery boxes 62 in each battery cluster 6. In the present embodiment, each battery cluster 6 includes one high-voltage box 61 and five battery boxes 62. Therefore, it can be understood that six small doors are arranged on one side of the battery cabin 11 to facilitate the maintenance of the high-voltage box 61 and the battery box 62.

[0077] See Figure 7 , Figure 7 is Figure 4 the top view of the mobile energy storage container. The pressure relief windows 7 arranged on the top of the box body 20 can be uniformly distributed in the longitudinal and transverse directions. In other words, the plurality of pressure relief windows 7 are arranged adjacent to each other along the longitudinal direction of the box body 20, and the pressure relief windows 7 are arranged at intervals along the transverse direction of the box body 20.

[0078] In the present embodiment, the pressure relief windows 7 are six in number. It should be noted that the specific number of pressure relief windows 7 can be set according to actual needs, which is not limited herein.

[0079] Referring to Figures 8 to 11 , Figures 8 to 11For another embodiment, a mobile energy storage container. In this embodiment, a plurality of battery clusters 8 are arranged in a first arrangement. Different from the first embodiment, the box 30 further comprises a busbar cabin 34. The busbar cabin 34 and the liquid cooling machine cabin 32 are respectively arranged at two ends of the box 30. That is, the busbar cabin 34 is arranged away from the front end and close to the rear end of the vehicle.

[0080] The busbar cabin 34 is provided with a busbar cabinet 9. The busbar cabinet 9 is electrically connected with each battery cluster 8. The busbar cabinet 9 has the functions of collecting and distributing electric energy, so that the mobile energy storage container can be connected with an external energy storage auxiliary system provided with a converter, a transformer, a control cabinet and the like, to realize discharging of the battery clusters 8 and power supply for electric equipment.

[0081] In some embodiments, the busbar cabin 34 is further provided with a base and a quick plug female socket 341. The busbar cabinet 9 is arranged above the base. The base comprises a receiving space. The quick plug female socket 341 is arranged in the receiving space. In the transverse direction of the box 30, both ends of the receiving space are provided with openings to facilitate the connection between the quick plug female socket 341 and each battery cluster 8.

[0082] The arrangement of the quick plug female socket 341 and the busbar cabinet 9 enables the user to realize charging and discharging of each battery cluster 8 in the mobile energy storage container. In addition, the busbar cabinet 9 is arranged close to the corner of the box 30, which can avoid wasting the internal space of the box 30 as much as possible, and this arrangement also facilitates the connection of the quick plug female socket 341 with external equipment through a cable, which is conducive to reducing the loss of the cable.

[0083] The busbar cabin 34 comprises a cabinet door 342 arranged on the side wall of the busbar cabin 34. The cabinet door 342 is arranged opposite to the opening to facilitate the use of the quick plug female socket 341. When the quick plug female socket 341 is not needed, for example, when the mobile energy storage container is moving with the vehicle, the cabinet door 342 is closed to facilitate the protection of the quick plug female socket 341. When the quick plug female socket 341 is needed, the user only needs to open the cabinet door 342.

[0084] In this embodiment, four pressure relief windows 311 are arranged. The four pressure relief windows 311 are staggered.

[0085] In addition, in this embodiment, the arrangement of the exhaust channel in the above-mentioned embodiment is cancelled, and the liquid cooling machine cabin 32 and the fire-fighting equipment cabin 33 are arranged adjacent to each other. That is, the liquid cooling machine cabin 32 and the fire-fighting equipment cabin 33 are separated by a separation structure.

[0086] An exhaust duct (not shown in the figure) is arranged in the fire-fighting equipment cabin 33. The exhaust duct is in communication with the battery cabin 31. Specifically, in the transverse direction of the box 30, both ends of the exhaust duct are connected with two side walls of the fire-fighting equipment cabin 33, respectively. The end of the exhaust duct close to the end wall is connected with an exhaust fan 343.

[0087] The exhaust ducts can be arranged in two, respectively close to the top and bottom of the fire-fighting equipment cabin 33, to increase the exhaust efficiency.

[0088] The arrangement of the exhaust ducts increases the space of the fire-fighting equipment cabin 33, which is conducive to placing more fire-fighting equipment in the fire-fighting equipment cabin 33, and also facilitates the installation and maintenance of the fire-fighting equipment in the fire-fighting equipment cabin 33 by the operator.

[0089] It should be noted that in the mobile energy storage container in which a plurality of battery clusters are arranged according to the second arrangement structure, a busbar cabin can also be arranged.
